Abstract: Aspects of the subject technology relate to electronic devices with pressure sensors. A pressure sensor in a portable electronic device may include an integrated heater or may be co-operated with an external heater for the pressure sensor. The heater may be operated to heat some or all of the pressure sensor for pressure sensor testing, calibration, or temperature-controlled pressure sensing operations.

Abstract: Aspects of the subject disclosure include a pressure-sensing device consisting of a housing including a membrane and one or more piezoresistive elements disposed on the membrane to sense a displacement due to a deflection of the membrane. A first set of electrodes is disposed over the membrane, and a second set of electrodes is disposed on a permeable port of the device at a distance from the membrane. The first and second sets of electrodes form an electrostatic actuator to exert a repulsive force onto the membrane to reduce the deflection of the membrane.

Abstract: Aspects of the subject technology relate to an apparatus including a housing, one or more piezoresistive elements and a magnetic actuator. The housing includes a membrane, and the piezoresistive elements are disposed on the membrane to sense a displacement due to a deflection of the membrane. The magnetic actuator is disposed inside a cavity of the housing. The magnetic actuator exerts a repulsive force onto the membrane to reduce the deflection of the membrane.

Abstract: A miniature gas sensing device includes a silicon-based substrate embedded with one or more heating elements. One or more electrodes are disposed on the substrate, and a semiconductor gas sensing layer is deposited over the substrate including over the one or more electrodes. The semiconductor gas sensing layer includes sensing grains forming a porous matrix, and a nanometer-scale barrier oxide layer deposited over the sensing grains. The barrier layer separates gas adsorption from surfaces of the sensing grains, and enables electron tunneling based charge transfer process from the sensing grains to the barrier oxide layer. The barrier oxide layer enhances the sensor stability and promotes signal selectivity by favoring detection of strongly oxidizing and/or reducing gas species over less reactive gas species.

Abstract: A miniature gas sensing device includes a silicon-based substrate embedded with multiple first heating elements. A number of electrodes are disposed on the silicon-based substrate. A gas-sensing layer covers the electrodes. A porous or mesoporous adsorbent layer selectively filters components of a gas mixture other than a target gas and allows the target gas to reach the gas-sensing layer. The first heating elements are operable to periodically regenerate sensing capabilities of at least the gas-sensing layer.

Abstract: A method is provided that includes reading a raw temperature value from a temperature sensor mounted in an electronic device and determining an amount of power applied to the electronic device. The method further includes generating, using a trained model, an ambient temperature value based on the raw temperature value and the determined amount of power, wherein the ambient temperature value represents a temperature outside of the electronic device.

Abstract: A portable communication device includes one or more miniature sensors to sense one or more environmental gases. A processor is coupled to the miniature sensors and is configured to enhance location detection by determining a sensor signal transition. The sensor signal transition is caused by subsequent exposures of at least one of the miniature sensors to environmental gases of a first air composition and a second air composition. The first air composition and the second air composition are respectively associated with a first location and a second location.

Abstract: Aspects of the subject technology relate to an apparatus having a housing including a port exposed to an environment. A pressure sensor is disposed within the housing to measure a pressure of the environment. A medium partially fills a sensor cavity or is coated over the pressure sensor, and a cap including multiple openings is disposed over the pressure sensor. The openings of the cap are arranged to be offset from the port.
